What is the impact of domain name hijacking on the website and how to prevent it?
Domain name hijacking is one of the methods used by black hat SEOs. By hacking other people’s websites and modifying other people’s website information, they can bring traffic to their own websites. The harm of domain name hijacking is much greater than that of snapshot hijacking, because the domain name has already been redirected. What exactly is going on, let’s take you to understand the relevant knowledge of “domain name hijacking”.
What is Domain Hijacking
Domain name hijacking, as the name suggests, is to hijack your domain name and get your domain name information, also known as web page hijacking and website hijacking, and is a common attack method on the Internet. By attacking the domain name resolution server or forging the domain name resolution server, the hacker redirects your website to the webpage designated by the other party after the user visits.
It is said that domain name hijacking is to intercept the request for domain name resolution within the scope of the hijacked network, analyze the requested domain name, and release the request outside the scope of review, otherwise it will directly return a fake IP address or do nothing to make the request unresponsive, its effect It means that a specific URL cannot be accessed or is a fake URL.
It is quite difficult to directly attack the analysis server. More hackers choose to attack the website directly, get the server or ftp permission or the background of the website, and then upload a domain name jump code (one sentence Trojan horse file), and then When a user visits a website, this file is executed to make the domain name jump.
Another simple hacker is to directly add a js jump code to the home page, and execute js to jump to other people’s web pages when visiting a web page. This method is easier to deal with, just delete the js code, but the first two This way is not easy to handle.
Impact of Domain Hijacking
The impact of domain name hijacking is very large. Users directly jump to very website pages through your website, which will not only deceive users, but also cause their website to lose a large number of users. Dangerous website ranks.
If the domain name is hijacked for a long time and the website is not adjusted in time, it is estimated that the later website will be scrapped, there will be no ranking and no traffic, basically the website will die, and the recovery period will be very long.
How to prevent domain name hijacking
Remove unnecessary services running on the DNS server, such as FTP, telnet, and HTTP.
Use firewall services on the network perimeter and DNS servers. Restrict access to those ports/services required for DNS functionality.
Restrict the modification of dns, add verification codes, password protection, etc. to improve security.
Restrict zone transfers to authorized devices only. Only a device is allowed to log in to modify it.
Strengthen the security of the website itself, keep the password and user name information properly, and make complicated settings.
Choose a service provider with higher security. If it is an unknown small service provider, the technology and hardware facilities may not meet the standard, and it is likely to be easily invaded by hackers and cannot be handled quickly. So don’t be greedy for cheap.
